Which muscle management style is most beneficial for a myoelectric prosthesis candidate in a TH amputation?

In the context of a transhumeral (TH) amputation, the myodesis technique often stands out as the most beneficial muscle management style for candidates of a myoelectric prosthesis. Myodesis involves directly anchoring the muscle and fascia to the residual bone at the time of surgery, which provides significant advantages in functional outcomes.

By utilizing myodesis, the muscle can maintain its position and innervation better, allowing for more effective contraction during prosthetic use. This enhanced muscular control translates into improved functional capabilities with a myoelectric prosthesis, as it allows for better transmission of muscle signals to the prosthesis. The direct connection helps to minimize the risk of muscle retraction or atrophy, both of which can compromise the functionality of the prosthesis.

Additionally, myodesis supports the natural movement patterns and enhances proprioceptive feedback, crucial for successfully operating a myoelectric device. This technique leads to more intuitive control over the prosthesis, thus providing a superior functional outcome and overall user satisfaction.

Other methods like myoplasty involve suturing opposing muscle groups together, which can provide some stability but does not offer the same level of muscle control and efficacy for myoelectric devices as myodesis does. Meanwhile, my
